Why is SO2 incorrect reagent to be used for the formation of BaSO4? It is soluble in water.... :(

no.....CO2 is correct for the formation of BACO3....but in the other part they asked about an aqueous reagent used for the formation of BASO4.....so for that I am asking why is SO2 not a correct reagaent?.....
